FDA Hits Respilon Production for 5 CGMP Violations
An FDA review of records provided by Respilon Production S.R.O., a producer of over-the-counter drugs in Jihomoravsky, Czechia, in response to the agency’s 5 /2/2025 request, found five significant violations of current good manufacturing practice (CGMP) regulations for finished drugs. A 4/20 Warning Letter says the specific violations were:
- failure to conduct at least one test to verify the identity of each component of a drug product, and failure to validate and establish the reliability of a component supplier’s test analyses at appropriate intervals;
- failure to establish and follow an adequate written testing program designed to assess the stability characteristics of drug products;
- failure to establish adequate written procedures for production and process control designed to assure that manufactured drug products have the identity, strength, quality, and purity they purport or are represented to possess;
- failure to establish and document the accuracy, sensitivity, specificity, and reproducibility of the company’s test methods; and
- failure to ensure that laboratory records include complete data derived from all tests necessary to ensure compliance with established specifications and standards.
FDA recommends that Respilon engage a qualified consultant to conduct a comprehensive six-system audit of its entire operation and assist it in meeting CGMP requirements. The firm was told to correct the violations promptly and to respond with a list of specific steps it has taken to address the violations and prevent their recurrence, with a schedule for completing the corrections.
